c't magazine has just published an English translation of an IOSlave tutorial written by Carsten Pfeiffer and Stephan Kulow. The article tells you everything you need to know to add support for new protocols to KDE. Examples covered include slaves that generate HTML and an ioslave for audio CDs. This is a great tutorial, so check it out and start coding!

Cool, this might actually inspire me to write some ioslaves. Maybe a cvs slave, maybe a SQL slave, or how about a remsh(rcp, rmv...) slave. Is there an rsync or ssh slave out there? I thought about an mtools slave, but I'm not sure if it would be usefull, maybe for unix platforms that don't do FAT. Would an rdf slave be silly?
...Actually I'm really way too lazy :( to write any of those, but I figured I'd suggest them anyway. :)

Another neat concept would be a scripting interface you could use to create ioslaves. I certainly would play around with that!
